i To all whom it may concern:

Be itknown that I, 0'1'10 Fox, a citizen of the United States, residing at Cleveland in the county of Cuyalioga. and State oi Ohio, have invented a certain new and useful Improvement in Water-Heaters of which the followina is a full, clear, an exact description, reterence being had to the i a water heater constructed in accordance with my invention; Fig. 2 represents a vertical sectional view through such a heater;

Fig. 3 represents a similar view taken at right angles to Fi 2; Fig. 4 is a side elevation of one of tie complete heating ele-' ments; Fig. 5 is a sectional detail illustrating the manner of connecting a pair of sections com rising an. element; and Fig. 0 is a sectiona detail of one end of one of the elements, showing the manner in which the header is connected thereto.

The heater exemplified herein consists generally of a;series of water circulating tl IHI'IIlH. each cl ment comprising a pair of H' 'llI-Ms' 'lctachably connected and ea h scclion u i tiug of" a iair of parallel conduit 1 iv transverse. duets or,

porti nconnected tubes, together with an inlet manifold or head r common to all the elements. an outlet manifold or header common to all the elemeats. together with casing walls and burn era arranged to heat the aforesaid elements.

llts't'llltlllfl the various parts in the drawings bv reference, characters, 1 denotes the base. oi the heater, said base being provided with a plate .2 above which there is located a series of burners 3. Each burner is provided in its top with suitable orifices 4 through which the mixture of gas and air may esca we and above which it may be ignited.

. ment.

sembled side by side,lthe lateral portions of thereof. One end of each conduit portion 8 is closed and one ofsaid portions is provided with a tubular connection 10, adjacent its closed end and projecting laterally therefrom and having a flange 11, by means of which the element may be secured to and may be). The opposite ends of the conduits 8 are open.

one. of such extensions being shown at 12 and the other extension at 13. The extencral tubular connection 14 having a tlan e 15 by means of which this section may e connected to a header (either outlet or inlet), the. header being arran ed on the reverse side of the heater from t. tat which carries the connection 10.

The conduit ortions 8 and 8 are prolti", said flanges being connected by means of bolts 17. The adjacent. portions of the portions 8 and 8 are contractwl. as shown more particularly in Fig. 5, and these contracted ends are provided each with an outwardly flared bore 18, 18", respectively. ada )tcd to engage correspondingly tapered suraces 19 and 19" of a double frnsto-conical nipple 20, the construction providing a arly effective knock-down connection bctween the two sections. When the sections have been assembled, as shown in Fig. 4 the conduit portions 8 and S" are secured together at their open ends so as to form in etl'ect but a sin le vertical conduit,

5 tion 0 bein having both ends close one of said conduits iaving a lateral connection at its upper end. and the other having a similar connection at its lower end.

' The water circulating element next adjacent to the element described is constructed in identical manner, with the exce ition that. the sections 6 and 7 are revcrseci, the secplaeed on top and the section also reversed.

The section 7 is similar to section 6 ex- 1 cept that the closed ends of the conduit. por- I tions 8 are provided with feet or extensions,

sion til is hollow and is provided with a latvided at their a jacent ends with flanges 18,

7 below, with their connections 10 and 14 the ducts of one element project into the space between the parallel side conduits of t. ie adjacent elements and overlap the ducts I placed in communication with a header, (either the inlet or the outlet, as the case the case, the conduit portions 8" carried by i In the construction shown herein, 21 (le notes the inlet header. This manifold is lorated at the bottom of the series of elements and is provided with a pair of vertical flanges 22 for each element, said flanges corresponding to the flanges 11 or 15 which thereto and being connected to the latter flanges by bolts 23. T e closed ends of the conduit portions 8 are provided each with a-flange 24 and the extensions of the closed ends of the conduit portions 8" are provided each with a similar flange 25. The flanges 24 and 25 are adapted to rest upon a shoulder 26 extending around the top' of the base outside of the vertically extending flange 27 and are also ada ted to receive and su port the cover 28. sai cover being prorit ed with a downwardl projecting flange 2t) and a seat or shoul or 30 within said flange, which sentor shoulder rests upon the projections 24 a and 25.

It will be noted that the transverse ducts ,1 9 and f) are equidistantly spaced when two sections are assembled. The member next adjacent to that shown in Fig. 4 will have the sections 6 and 7 reversed.

Such being the lower section 7 of such adjacent element may be on the heating element adjacent will be elevated with respect to those car- 5 ried by'the element Just described, such elevation bein cause .by the extensions 12 and 13. Itt erefore follows that the transl verse ducts 9 will be elevated in like man- 1 may be used in a heater.,

I nor. This arrangement appears clearly in i t Fig. 8. The third element is assembled in 1 l the same manner as is the first, the fourth element in the same manner as the second, l

and so on, for any number of elements that i bliug the elements insures the provision of spaces between the transverse ducts of each e cment into which the wings or side projectious of the similar ducts on the adjacent sections may extend. The conduits 8, 8" plurcd side by side constitute one pair of opposed walls for the heater casing, the nilltl pair of opposed walls consisting of easing members 31 min ited to be inserted between the seats 26 nut 30. Each of these members is provided with a series of ribs or flanges 32 projecting inwardly therefrom into the space provided between the adjacent transverse ducts fl, and t), the wings of said ducts ovcrhan iug said ribs or flanges.

33 denotes t ie outlet header or manifold. This is located at the top of the heater and is provided with vertically arranged pairs of flanges M which are adapted to be secured to the flanges 1t and 15 at the upper 3 The cover 28 is provided wit h a central outlet fine 35, said flue being provided with a draft-equalizing plate 36. This plate;

- is analogous in construction to an inverted table, bein provided with a short skirt 37 I and with s iort legs 38. The legs are adapted to bear against the cover 28 to s )ace the 'draft equalizer therefrom, said equa izer bein secured to the cover by means of bolts39. QVith a device constructed as described, the operation is as follows: The water flows from the inlet manifold 21 into the lower 5 ends of the. vertical conduits 8, 8", and I through the transverse ducts 9, 9", into the rear series of vertical conduits, being discharged from those conduits into the outlet manifold 38. It will be noted that each burner 3 is uri'an ed directly beneath a heater element and cneath the downwardly extending portion of the duct 9 or 9 thereabovc. The products of combustion from each burner rise against the downwardlydirected portion of the duct thereabove and 1' are divided thereby, passing outwardlyi around the wings fl and passing into the narrow spaces between the win s of the? ducts thcreabove and the overlapping wings The construction rovidcs a series of tortuous passageways ti'rough which the prodacts from the burners pass upwardly to the outlet 35, the arrangement being such that the heat units develo )ed from the combustion are largel absor )ed beforethe products are discharget through the flue and an extremely eflicient heating of the water is secured. As there will be a tendency for the products from the burners 'nearest to the middle of the heater to ass up with greater rapidity to the contra flue 3 5, the draft. equalizer 38 is provided. This causes the roducts passin u iwardly from the central burners to be e ected outwardly around the edges of the plate before they may pass to the outlet flue, thus securing practically the same rate of speed for the products of combustion from all of the burners and 37 forms, with the p ate 36, a shallow cup i or receptacle in which water of condensation mav collect.

It will be noted that the ducts 9 and 9 have a slight upward inclination from the i inlet side of the heater toward the outlet Masai 3 side. This inclination prevents the water 1 from being pocketed in the heater, reduces friction,

and facilitates the circulation therethrough. When the heater is used in connection with a vapor heating system, the water will stand at about the height indicated by the line a-a on Fig. 2. Under i the influence of the heat from the burners, the water circulates through the inclined ducts 9 and 9' from the inlet side toward the outlet side, the colder water dropping back to the bottoms of the vertical conduits on the inlet side of the heater, a continuous circulation occurring. When the heater is filled with water, the carrying of the outlet vertical conduit to a higher point than the conduit on the other or inlet side revents the accumulation and poeketin 0 air at the up 70! end of the latter con nit.

The water above described is simple and economical of construction, the parts thereof being easily made as castings; the parts are easily and uickly assembled and disassembled, and the heater as a whole is extremely eflicicnt in operation.
